Abstract

The invention relates to a device for dynamic control of a water flow, comprising the following items in a body (1): a feed chamber (13), a discharge chamber (7) and a piston (8) arranged between the feed chamber (13) and the discharge chamber (7). The piston can be displaced from a first position, which is offset towards the feed chamber (13) and wherein the piston (8) narrows the flow between the feed chamber (13) and the discharge chamber (7), and a second position, which is offset towards the discharge chamber (7) and wherein the piston (8) does not narrow the flow between the feed chamber (13) and the discharge chamber (7).

Claims (13)

1. Equipment for the dynamic control of a flow, comprising one body (1) a supply chamber (13), a discharge chamber (7), a piston (8), which is arranged between the supply chamber (13) and the discharge chamber (7) and which is traveling between a first position, which is shifted toward the supply chamber (13), whereby this piston (8) in the first position narrows the flow between the supply chamber (13) and the discharge chamber (7), and a second position, which is shifted towards the discharge chamber (7), whereby the piston (8) in the second position does not narrow the flow between the supply chamber (13) and the discharge chamber (7), and a recuperating spring (17) which impinges on the piston (8) towards the first position, whereby the piston (8) comprises a cylindrical casing section (9) interspersed by radial passages (10; 20), and a transverse section (12) which is interspersed by an axially delimited passage (11), characterized in that the supply chamber (13) is at least partially ring-shaped and surrounds the piston (8), in that in the interior of the piston (8) an intermediate chamber (16) is arranged downstream from the supply chamber (13) which is delimited by the casing section (9) and the transverse section (12), and communicates in the first position of the piston (8) via the radial passages (10; 20) with the supply chamber (13), and that the limited radial passages (10; 20), the axially delimited passage (11), and the recuperating spring (17) are thus proportioned relative to each other, that the effect of the spring (17) essentially corresponds to the force, which tends to shift the piston (8) from the first position into the second position, when the maximum flow is let off, which may cause an instability in a thermostatic mixer.
2. Equipment according to claim 2, characterized in that the limited passages are formed by recesses (10) which are provided at the edge of the end of the casing (9).
3. Equipment according to one of the preceding claims, characterized in that the limited passages are formed by holes (20) which are provided in the casing (9).
4. Equipment according to claim 1, characterized in that in addition to the limited passages or instead of them, an intermediate space between the body and the piston are provided.
5. Equipment according to claim 1, characterized in that the intermediate chamber (16) is delimited by a supply port (3), in which an inlet chamber (5) is defined and which has axial passages in the periphery (2) which end in the ring-shaped supply chamber (13) surrounding the piston (8).
6. Equipment according to claim 5, characterized in that the inlet chamber (5) and the axial passages in the periphery (2) are formed by passages which are realized in an additional element, that is inserted between the body (1) of the equipment and the supply port (3), whose part it forms.
7. Equipment according to claim 7, characterized in that the additional element is manufactured from punched plastic material.
8. Equipment according to claim 5, characterized in that the piston (8) in its closed position sits on a level surface of the supply port (3).
9. Equipment according to claim 5, characterized in that the piston (8) in its first closed position partially engages into a seat which is formed in a level surface of the supply port (3).
10. Equipment according to claim 5, characterized in that the supply port (3) has a projecting part (23) which slides into the limited passage (11) and closes this partially when the piston (8) is in its first position, and doesn't close it when the piston (8) is in its second position.
11. Equipment according to claim 1, characterized in that it is installed into a stop cock.
12. Equipment according to claim 11, characterized in that the direction the piston (8) is shifted to, coincides with the axis of a closing element (18) of the stop cock.
13. Equipment according to claim 1, characterized by its installation in series in the cold water supply of a thermostatic mixer for its stabilization.
